FOLDING COT.

SPECIFICATION forming part of Letters Patent N 0. 708,869, datedSeptember 9, 1902.

7 Application filed October 9, 1901. Serial No. 78,073. (No model.)

To aZZ whom it may concern:

Be it known that I, 'JOfiEPH' DAVIDOFF, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn,

' in the county of Kings and State of New York,

have invented a new and Improved Folding Cot, of which the following isa full, clear, and exact description.

The object of the invention is to provide a new and improved folding cotwhich is simple and durable in construction, composed'of comparativelyfew parts, not liable to get out of order, readily set up, and adaptedto be folded in very little space.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all thefigures.

Figure 1 is a side elevation of the improvement with the parts slightlytilted up. Fig. 2 is an end elevation of the same. Fig. 3 is an enlargedcross-section of one of the collars in the fork of a supporting-arm.Fig. 4 is an enlarged transverse section of the reach, one of thehea(ls,and its supporting arms and legs.

.Fig. 5 is a longitudinal sectional elevation of the same. Fig. 6 is anenlarged side elevation of the reach and part of its joint shown insection. Fig. 7 is a side elevation of the reach, the heads,supporting-arms, and legs in the folded position; and Fig.8 is a likeview of the side rails and the mattress in a folded position. I

The improved folding cot consists, essentially, of a reach A, carryingat its ends heads B, each of which is provided with pivoted legs(Lextending downwardly and outwardly, and supporting-arms D, extendingupwardly and outwardly. The outer ends of the supporting-arms D areprovided with forks E, adapted to receive collars F, attached to theside rails G, carrying the mattress H, of afabric or other suitablematerial.

The reach A is preferably made in two or more sections A A provided atadjacent ends with blocks A A pivotally connected with each other bylinks A to allow of folding the sections A and A as plainly illustratedinFig. 7. A dowel-pin A is carried on one of the blocks to engage arecess in the other block and securely hold the blocks in a lockedposition at the time the reach-sections are extended, as plainly shownin Fig. 1.

The legs 0 and the arms D are pivoted on the headsBand rest againstflanges B,formed on the outer ends of the heads, the latter screwing onthe outer threaded ends of the reach A, as plainly indicated in Fig. 1.Washers B are mounted to turn on the reach A and engage the heads at theinner faces thereof to hold the legs and arms in an extended positionbetween the flanges B and the washers, each of the latter resting on acollar A", formed on the reach A. The washers B are provided with slotsb, adapted to register withthe legs 0 and arms D to permit of foldingthe said legs and arms on the reach. (See Fig. 7.)

Each of the collars F has its main body F made polygonal, as indicatedin Fig. 3, to fit the correspondingly-shaped side Walls E of the fork E,and each collar F is provided with two flanges FF, forming a groove withthe body of the collar and reaching opposite sides of the wall E, butextending within segmental flanges E arranged on the said forks.

When it is desired to stretch the mattress H more tightly, it is onlynecessary to turn the side rails G to wind up some of the mattressmaterial on the side rods and then press the collar-bodies Finto theside walls E of the forks to hold the side rails against turning andunwinding of the mattress H. By having the forks and collars arranged asdescribed the side rails are prevented from longitudinal shifting, aswell as from turning on their own axes. Asindicated in Fig. 1, each ofthe side rails G is preferably made in sections connected with eachother. by joints G, similar to the joints of the reachsections A A sothat further description of the joints G is not deemed necessary. Eachof the forks E is provided at the inside with a socket E forreceiving-posts K, adapted to support a canopyor the like.

-When it is desired to set up the cot, then the reach A is extended, asshown in Fig. 1, and the legs 0 are swung outward and downward to reston the floor or other support, while the arms D are swung outward andupward to bring the forks into position to receive the collars F on theextended side rails G. The several parts are now securely extended andare not liable to collapse when the mattress is occupied by a person.

\Vhen it is desired to fold the cot, the collars F are disengaged fromthe forks E, and then the sections of the side rails G are folded up andthe mattress rolled upon the folded section, as indicated in Fig. 8. Theoperator now turns the washers 13 to bring their slots 1) into registerwith the arms D and legs 0 to allow of swinging the arms D and the legs0 inward upon the reach-sections A A and then the operator folds thereach, as illustrated in Fig. 7. The entire cot now consists of twobundles, which can be conveniently carried about.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A folding cot, comprising side rails for carryinga mattress, collars secured on the outer ends of the rails and havingside flanges, supporting-arms for the side rails having forks at one endfor engagementwith the collars between the flanges, the forks havingsegmental flanges within which the flanges of the collars extend, as setforth.

2. A folding cot, comprising side rails each made in sections hingedtogether, collars secured on the sections of theside rail and havingpolygonal bodies and side flanges, and supporting-arms each having afork at its outer end having its inner side walls shaped to correspondwith the body of the collar, the forks being provided with segmentalflanges, the flanges of the collars extending on opposite sides of thewalls of the fork but within the segmental flanges on said forks, as setforth.

3. A folding cot having side rails, a mattress secured to the said siderails, collars secured on the side rails and having polygonal bodies andside flanges, and supporting-arms formed at their outer ends with forkshaving correspondingly-shaped side walls, walls into which fit the saidcollar-bodies, each fork being formed with a segmental flange theflanges of the collars extending 011 opposite sides of thepolygonalshaped walls of the forks but within the segmental flanges ofsaid forks, as Set forth.

4. A folding cot, comprising a reach, heads held on the ends of thereach, legs pivoted on the said heads, supporting-arms pivoted on thesaid heads and having receiving-forks at their outer ends, side barshaving collars for engaging the said forks, and a mattress carried bythe said side bars, as set forth.

5. A folding cot, comprising a sectional folding reach, heads secured onthe ends of the reach, legs pivoted to the heads and ex tending radiallyoutward and downward, supporting-arms pivoted on the heads and extendingradially therefrom in an outward and upward direction, forks at theouter ends of the supporting-arms, side rails made in folding sectionsand having collars for engaging the said forks, and a mattress securedto the said side rails, as set forth.

6. A folding cot, comprising areach, heads held on the ends of thereach, legs pivoted on the said heads, supporting-arms pivoted on thesaid heads, side bars, and a mattress carried by the side bars, the saidsupportingarms and side bars being provided with engaging means, as setforth.

7. A folding cot, comprising a reach, heads screwing on the outerthreaded end of the reach, flanges formed on the outer ends of theheads, washers mounted to turn on the reach and engaging the heads atthe inner faces thereof, collars on the reach and engaging theWashers,the said washers being'provided with slots, legs pivoted on theheads between the flanges and the washers, supporting-arms pivoted onthe heads, side bars adapted to be supported by said arms, and amattress carried by the said side bars, the slots of the washers beingadapted to register with the supporting arms and legs to permit offolding the arms and legs on the reach, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH DAVIDOFF.
